This study aimed to investigate the differences in maximal oxygen uptake (V̇O2max ) and submaximal thresholds between a standard graded exercise test (GXT) and a perceptually regulated graded exercise test (PRGXT) in trained runners. Eleven well-trained middle- to long-distance runners performed both tests in a randomized order. PRGXT used incremental "clamps" of rating of perceived exertion (RPE) over 10×1-min stages on an automated treadmill equipped with a sonar sensor allowing them to change their running speed instantly and in a natural way...

We investigated whether heart rate (HR)-derived parameters are accurate performance predictors in endurance recreational runners. One hundred thirty recreational athletes completed an incremental running test (4´running + 1´rest). After each stage, we recorded HR, % of maximum HR (%HRmax), and blood lactate. We also assessed HR after each recovery period, and calculated lactate and HR recovery thresholds and HR deflection point. We tested these parameters for associations with running performance, as measured by peak treadmill speed (PTS) and personal best International Association of Athletics Federations (IAAF) score...

Light Absorbing Aerosols (LAA) absorb sunlight and heat the atmosphere. This work presents a novel methodology to experimentally quantify the heating rate (HR) induced by LAA into an atmospheric layer. Multi-wavelength aerosol absorption measurements were coupled with spectral measurements of the direct, diffuse and surface reflected radiation to obtain highly-time resolved measurements of HR apportioned in the context of LAA species (Black Carbon, BC; Brown Carbon, BrC; dust), sources (fossil fuel, FF; and biomass burning, BB), and as a function of cloudiness...

BACKGROUND AND OBJECTIVES: We evaluated the effect of re-resection with wide margins (undertaken because initial resection performed elsewhere was incomplete) on survival in patients with spermatic cord sarcoma (SCS). METHODS: After excluding those with metastatic disease and those not undergoing surgical intervention, the records of 72 consecutive patients treated for SCS between 1981 and 2011 at Memorial Sloan Kettering Cancer Center were reviewed. Recurrence-free survival (RFS) and cancer-specific survival were calculated using the Kaplan-Meier method for comparing between the 48 patients who underwent wide re-resection (WRR) within 5 months of diagnosis and the 24 who did not...
